A powerful earthquake shook central Myanmar on Wednesday, damaging nearly a hundred ancient Buddhist pagodas in the former capital of Bagan, a major tourist attraction, officials said.

The U.S. Geological Survey said the magnitude 6.8 quake was centered about 25 kilometers (15 miles) west of Chauk, an area west of Bagan. It was located fairly far below the Earth's surface at a depth of about 84 kilometers (52 miles), it said. Deep earthquakes generally cause less surface damage.

At least 94 brick pagodas in Bagan were damaged, the Ministry of Religious and Cultural Affairs said in a statement. Bagan, also known as Pagan, has more than 2,200 structures including pagodas and temples constructed from the 10th to the 14th centuries. Many are in disrepair while others have been restored in recent years, aided by the U.N. cultural agency UNESCO.

The vast site is the country's premier attraction for tourists, who can view a panorama of temples stretching to the horizon flanked by the mighty Irrawaddy River, an especially impressive experience at sunset.

Dr. Myo Thant, general secretary of the Myanmar Earthquake Committee, said other areas apparently were not badly affected and there were no reports of deaths.

However, police officer Htay Win in Pakokku, about 70 kilometers (45 miles) from the epicenter, said one person there had been killed and one injured. "The person was killed by falling bricks from a building," he said.

Vincent Panzani, a staff member in Pakokku for the aid agency Save the Children, said several of his colleagues from the area said it was the strongest earthquake they have experienced.

"We felt quite heavy shaking for about 10 seconds and started to evacuate the building when there was another strong tremor," he said in comments sent by email. "Most of the reports of damage have been to the pagodas in the area with dozens impacted. There have also been reports of damage to smaller, more basic buildings including a collapsed wall and a destroyed roof."

Worried residents of Yangon, the country's main city, rushed out of tall buildings, and objects toppled from tables and from Buddhist shrines in homes. However, there were no immediate reports of serious damage in the city.

The quake was also felt in a half dozen states in neighboring India, where people rushed out of offices and homes at several places. It caused buildings to sway in Bangkok, Thailand's capital, several hundred kilometers (miles) to the east. There were no immediate reports of damage in either country.

The last major quake in the area — which is often affected by smaller tremors — occurred in April about 300 kilometers (180 miles) further north, and measured magnitude 6.9. It caused no reported casualties and only minor damage.
